Towing Rules
A clearer guide to UK towing law for trailers, caravans and motorhomes, including licence rules, weight limits, size limits, safety checks, FAQs and A-frame basics.
Towing can make a motorhome setup more flexible, whether you want to carry extra gear, tow a small trailer, or travel with a caravan or car where legally permitted. The important point is that UK towing law depends on more than one factor. Your licence, your vehicle limits, the trailer weight, the tow bar rating and the full combined weight all matter.
This page brings the main rules together in a cleaner format so they are easier to check before you travel. It is a practical guide for Roller Team owners and should be used alongside current official DVLA, GOV.UK and manufacturer guidance for your exact vehicle and trailer combination.
Check first
- Your driving licence entitlement
- Your motorhome’s towing capacity
- The trailer or caravan plated weight
- The gross train weight limit
- Tow bar and noseweight limits
- Insurance cover for towing
Common towing uses
- Small luggage or utility trailers
- Motorbike trailers
- Cycle or leisure equipment trailers
- Caravans towed by suitable vehicles
- Car trailers where permitted
- Extra storage for longer trips
Driving licence requirements
Your licence category is one of the first things to check. UK towing rules have changed over time, so what you can tow depends on when you passed your test and what categories appear on your licence. Even where your licence allows towing, you must still stay within the legal limits for the vehicle, trailer and full combination.
If your motorhome is over 3.5 tonnes, separate licence rules may also apply to driving the motorhome itself. In practice, you may need to confirm both your entitlement to drive the vehicle and your entitlement to tow with it.
If you passed after 1 January 1997
Check the current DVLA rules for the combinations you are allowed to drive. In many cases, category B drivers can tow, but the vehicle and trailer must remain within the permitted limits. The manufacturer’s towing capacity still applies even if your licence allows towing.
If you passed before 1 January 1997
Older licences may include broader entitlements, but it is still important not to rely on assumptions. Always check the categories shown on your licence and confirm the current rules for motorhomes, trailers and caravans before towing.
The key rule is simple
Your licence may allow towing, but your motorhome, tow bar, trailer and plated weights must all work together legally and safely.
Towing weight limits
When towing, several different weight figures matter. These are usually found on the vehicle plate, trailer plate, handbook or tow bar documentation. Towing legality is based on more than one number, so it is important to check the full set of limits rather than focusing on a single figure.
- Maximum authorised mass (MAM): the maximum legal weight of the vehicle or trailer when fully loaded.
- Gross vehicle weight (GVW): the maximum permitted weight of the motorhome itself.
- Gross train weight (GTW): the maximum permitted combined weight of the motorhome and trailer together.
- Braked trailer limit: the maximum trailer weight the vehicle can tow when the trailer has its own brakes.
- Unbraked trailer limit: the lower limit for trailers without brakes.
- Noseweight: the downward force the trailer places on the tow ball.
Even if one figure looks acceptable, the full combination must still stay within all relevant limits. A motorhome can also run close to its own weight limit before a trailer is attached, so passengers, water, food, bikes, accessories and luggage all affect the available towing margin.
Motorhomes
Motorhomes often run close to their weight limits before towing begins. If you are unsure, weigh the vehicle properly in travel-ready condition rather than relying on estimates.
Trailers and caravans
The trailer or caravan plated weight matters, not just what you think it currently weighs. It also needs to be loaded correctly, balanced properly and matched to the towing vehicle for stable handling.
Trailer and caravan size limits
Size limits matter as well as weight. The legal limits can depend on the type of towing vehicle and trailer, so always confirm the current rules for your setup before travelling. As a practical rule, longer and wider combinations are harder to manoeuvre, need more turning space and may affect route planning, campsite access and ferry bookings.
- Check the trailer or caravan width and overall length against current UK rules.
- Include anything that changes the effective size of the outfit, such as storage boxes or mounted equipment.
- Allow for extra tail swing, wider cornering and longer stopping distances.
- Review access carefully if you are travelling on narrow roads, using older campsites or planning European routes.
Towing safety tips
Good towing is not just about what your motorhome can pull. It is also about stability, braking, loading, visibility and confidence behind the wheel. A few careful checks before each trip can make a big difference.
Before you set off
- Check the tow bar is approved for your vehicle and rated correctly.
- Confirm the trailer lights, indicators and number plate are working.
- Make sure breakaway cables or secondary couplings are fitted correctly.
- Check tyre pressures on both the motorhome and trailer.
- Load heavy items low and keep weight balanced.
On the road
- Do not exceed axle limits, even if the total weight seems acceptable.
- Allow longer stopping distances and wider turning space.
- Take extra care in crosswinds, on descents and when overtaking.
- Plan fuel stops, parking and campsite access with the full outfit in mind.
- Review your insurance before towing abroad or carrying high-value equipment.
Towing FAQs
Can I tow with a standard car licence?
Often yes, but only within the current licence rules and the manufacturer’s limits for the vehicle and trailer combination. Always check your licence categories and the latest DVLA guidance.
What matters more, actual weight or plated weight?
Both matter, but plated limits are critical because they define the legal maximums. You must not exceed the relevant plated limits, and the real loaded weight must also remain within those limits.
Do I need to check noseweight?
Yes. Noseweight affects stability and must stay within the limits for the motorhome, tow bar and trailer coupling.
Can I tow abroad under the same rules?
Not always. Local speed limits, equipment requirements, reflective markings and documentation can vary by country, so check the rules before travelling.
A-frames
A-frames are often discussed by motorhome owners who want to tow a small car. This area can be more complicated than standard trailer towing because the legal position may depend on how the towed vehicle is classified, whether braking requirements are met and where you are travelling.
In practical terms, treat A-frame towing with extra caution. Check current UK guidance, confirm the braking setup is compliant, and be especially careful if you plan to travel outside the UK, where enforcement and interpretation may differ.
Final thoughts
Towing can make your motorhome setup more versatile, but only when the full combination is legal, safe and suited to the way you travel. The best approach is to check your licence, confirm the manufacturer’s limits, understand the plated weights and avoid assumptions.
If you are ever unsure, pause and verify the details before setting off. A few checks in advance are far easier than dealing with instability, damage or enforcement issues on the road.
